<div dir="ltr">The problem is that wire nuts are not intrinsically sound, a good connection depends on the skill of the craftsman. They are not legal under the British electrical code, where I did my training, wires need to be firmly held under a screw as in a terminal. The US would be better to get rid of these nasty devices.<div>In Britain, you see these terminal strips used. As long as they stay dry, they last forever.</div><div><a href="http://my.rs-online.com/largeimages/R4649744-01.jpg">http://my.rs-online.com/largeimages/R4649744-01.jpg</a><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Sep 6, 2016 at 3:19 PM, MDElectricSolar . <span dir="ltr"><<a href="mailto:mdelectricsolar@gmail.com" target="_blank">mdelectricsolar@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-size:small">Yes, wire nuts, and loose connections are a big issue in AC circuits as well.

It comes up every so often and with DC, I will not use, approve or pass any wire nuts on any DC side. Some say its OK but the facts are they will fail, this connection was just six years and when l opened the junction box it was glowing and by the looks of it has for some time. There are 8 strings 2 per string and thats a 12.5 % failure rate (the other one was completely distroyed) not to mention the fire hazard in a PVC junction box.<br>
Please pass this along and tell everyone to stop using these. <br>
